Adam Clarke

For I will not dare to speak - If the thing were not as I have stated it, I would not dare to arrogate to myself honors which did not belong to me. But God has made me the apostle of the Gentiles; and the conversion of the Gentiles is the fruit of my ministry, Christ having wrought by me for this purpose. By word and deed - Αογῳ και εργῳ· These words may refer to the doctrines which he taught and to the miracles which he wrought among them. So they became obedient to the doctrines, on the evidence of the miracles with which they were accompanied.
